Wherein the sludge discharge centrifuge 6 is a small-sized centrifuge; activated sludge is filled in the anaerobic tank 3, the first aerobic tank 4 and the second aerobic tank 5; the reaction chamber 8 is filled with a reactant.

The sewage suction pipeline 9 pumps the sewage into the anaerobic tank 3 through the water suction pump 10, and the anaerobic bacteria in the anaerobic tank 3 release phosphorus in the sewage through a hydrolysis stage, an acidification stage and a methanation stage, and simultaneously ammoniate partial organic matters. The sewage in the anaerobic tank 3 passes through the first aerobic tank 4, and the microorganisms in the first aerobic tank 4 decompose the organic matters in the sewage into inorganic matters and degrade ammonia nitrogen in the sewage. Because the organic load of the first aerobic tank 4 is higher, a large amount of organic matters need to be decomposed, and the ammonia nitrogen removal effect is poor, the water in the first aerobic tank 4 enters the second aerobic tank 5, the organic load of the second aerobic tank 5 is smaller, and ammonia nitrogen in the water can be further degraded.

The sewage in the second aerobic pool 5 flows into a sludge discharge centrifuge 6, the sludge discharge centrifuge 6 generates centrifugal force through rapid rotation to separate sludge from water in the water, the water after separating the sludge enters a settling tank 7 for further settling and then enters a reaction tank 8, a reactant in the reaction tank 8 reacts with organic phosphorus dissolved in the sewage to generate metal phosphate which is insoluble in water, and finally, cleaner water is obtained and discharged through a drainage pipeline.

In this example, the reactant is a ferric sulfate reagent, and in another embodiment, the reactant may be a metal salt such as quicklime or aluminum sulfate, and forms a metal phosphate that is hardly soluble in water by reacting with organic phosphorus in the sewage.
